The SpaceX Kestrel was an LOX/RP-1 pressure-fed rocket engine. The Kestrel engine was developed in the 2000s by SpaceX for upper stage use on the Falcon 1 rocket. Kestrel is no longer being manufactured; the last flight of Falcon 1 was in 2009. Kestrel was built around the same pintle architecture as the SpaceX Merlin engine but does not have a turbopump and is fed only by tank pressure. Thrust vector control is provided by electro-mechanical actuators on the engine dome for pitch and yaw. Roll control (and attitude control during coast phases) is provided by helium cold gas thrusters.

  • Das Raketentriebwerk Kestrel (englisch für den Buntfalken, Turmfalken und verschiedene andere kleine Falkenarten) ist ein druckgefördertes LOX-/RP-1-Flüssigkeitsraketentriebwerk. Das Triebwerk Kestrel wurde von der US-amerikanischen Firma SpaceX für die Anwendung in der Oberstufe der Rakete Falcon 1 entwickelt. (de)
  • Mesin 'Kestrel adalah sebuah mesin roket tekanan LOX/RP-1. Mesin Kestrel dikembangkan oleh SpaceX untuk digunakan tahap atas pada roket Falcon 1. Kestrel dibangun sekitar arsitektur yang sama sebagai mesin Space X Merlin tetapi tidak memiliki pompa turbo dan hanya diberi dengan tekanan tangki. (in)
  • Le moteur Kestrel est un petit moteur-fusée de faible poussée utilisant comme ergol un mélange oxygène liquide/kérosène injecté grâce à la pressurisation des réservoirs. Il a été développé par SpaceX pour propulser l'étage supérieur de son lanceur léger Falcon 1. Sa poussée dans le vide est de 31 kN soit 3,1 tonnes et sa masse est de 52 kg. (fr)
  • ケストレル (Kestrel) とは、アメリカの民間企業スペースX社が開発したロケットエンジンである。推進剤としてはケロシンのRP-1と液体酸素の組み合わせを使用し、ファルコン1ロケットの上段用エンジンとして使用されていた。 (ja)
  • Kestrel (pol. pustułka) — silnik rakietowy produkowany przez prywatną firmę astronautyczną SpaceX. Jednokomorowy, napędzany mieszaniną ciekłego tlenu (LOX) i kerozyny (RP-1). (pl)
  • Kestrel var en flytande syre/RP-1 tryckmatad raketmotor. Kestrelmotorn utvecklades under början av 2000-talet av SpaceX för andra steget på företagets Falcon 1-raket. Kestrelmotorn tillverkas inte längre och den gjorde sin sista Falcon 1-flygning den 14 juli 2009. (sv)
  • Kestrel火箭发动机是一款使用液氧和煤油作为燃料的挤压循环火箭发动机。 Kestrel火箭发动机于21世纪00年代由SpaceX开发,用于猎鹰1号运载火箭火箭的上面级。Kestrel使用了与默林火箭发动机相同的针栓式喷注器,但并没有涡轮泵,只靠储箱压力供应推进剂。 Kestrel在燃烧室与喉管处采用烧蚀冷却,在喷管处采用辐射冷却。喷管由高强度铌合金制成。作为金属,铌比起碳-碳来说更不易开裂。根据SpaceX的说法,与空间碎片或是第一级的碰撞可能会产生凹陷,但对发动机性能没有明显影响。通过在烧蚀冷却和辐射冷却的交界处使用钛制热交换器,大大地提高了氦气用于加压的效率。 推力矢量控制由发动机整流罩上的电子-机械式执行机构提供俯仰、偏航控制。滚转(以及滑行阶段)控制由氦气冷气推进器提供。 一套TEA-TEB点火系统用于提供多次点火能力。在多星任务中这一设计可以用于在不同高度与轨道倾角放置卫星。 (zh)
  • Raketový motor Kestrel je poháněn směsí tekutého kyslíku a RP-1 a byl vyvinut společností SpaceX v roce 2000 pro horní stupeň rakety Falcon 1. Kestrel je postaven na stejné architektuře vstřikovače, jako Merlin, ale nemá turbočerpadla, palivo je vháněno pouze tlakem z nádrží Řízení vektoru tahu je provedeno elektro-mechanickým pohonem a řízení polohy je provedeno tryskami se stlačeným heliem. TEA-TEB pyroforický zapalovací systém zajišťuje restartovatelnost druhého stupně. Toho by bylo využito při vynášení více položek nákladu na dráhy s odlišnými parametry. (cs)

  • Il motore a razzo Kestrel è un propulsore per uso aerospaziale alimentato da una miscela LOX/RP-1 sviluppato agli inizi degli anni 2000 dalla SpaceX per essere usato sul razzo vettore Falcon 1. Il Kestrel è stato costruito utilizzando la stessa architettura di iniezione del carburante dei motori della famiglia Merlin, ma non ha una turbopompa ed è quindi alimentato solo dalla pressione dei serbatoi.
